Answer:

b. aluminum

Explanation:

The specific heat capacity is defined as the amount of heat required to raise the temperature of 1g of a material in 1°C.

Thus, the sample with the higher specific heat capacity is the sample that will require more energy to increase its temperature in 1°C, suffering the smallest change in temperature.

Thus, is the aluminium with 0.900J/gK the element that is most likely to undergo the smallest change in temperature:

3. If 175 grams of nitrogen reacted with hydrogen to make hydrogen, how much ammonia would be needed?
zmey [24]

Answer:

37.5 g of H₂

Explanation:

N₂ (28g) + 3H₂ (6g) => 2NH₃ (34g)

Every 28g of N₂ needs 6g of H₂

=> Every 7g of N₂ needs 1.5g of H₂

=> 175g of N₂ needs 1.5 x 25 g of H₂

=> 37.5 g of H₂

Even though we have known of many nuclear energy technologies for about one century some of these technologies have not yet been
Romashka [77]

<u>Answer:</u> The nuclear fission reaction of U-234.043 is written below.

<u>Explanation:</u>

In a nuclear reaction, the total mass and total atomic number remains the same.

For the given fission reaction:

^{234.043}_{92}\textrm{U}\rightarrow ^{137.159}_{54}\textrm{Xe}+^{A}_{38}\textrm{Sr}+3^{1.0087}_0\textrm{n}+180MeV

<u>To calculate A:</u>

Total mass on reactant side = total mass on product side

234.043 = 137.159 + A + 3(1.0087)

A = 93.858

Now, the chemical equation becomes:

^{234.043}_{92}\textrm{U}\rightarrow ^{137.159}_{54}\textrm{Xe}+^{93.858}_{38}\textrm{Sr}+3^{1.0087}_0\textrm{n}+180MeV

Hence, the nuclear fission reaction of U-234.043 is written above.
